PROC SQL: Delete rows in which two date fields differ by more than 250 days

Posted on 2009-05-18
Last Modified: 2012-05-07
Hi all, I;m not familiar with PROC SQL (I think its similar to MS SQL)

I am running a statistics program called SAS and am trying to delete certain rows in a database. The fields 'Date_Announced' and 'Date' are the ones I am concerned with. I'm trying to subtract the two coloumns and then delete the rows for which the result is >250 . The sheet is called Asx.mergernew.

Can someone help me with the exact command to type into my command window?

you can do something like:

delete from YourTableName where DATEDIFF(dd,Date_Announced,[date])>=205

if you want in stored procedure than use this one.

create proc DeleteRecord
delete from YourTableName where DATEDIFF(dd,Date_Announced,[date])>=205
--run abov proc
exec deleteRecords

Open in new window

HI RiteshShah

DATEDIFF is not a command that is recognised nor is it a field. Is there a way to get around this? One field in ours is Date and the other is Date_Announced. What is dd?

DATEDIFF is a date function built in in SQL Server, "DD" gives you difference in days.

can't you even run below command?

select DATEDIFF(dd,getdate()-250,getdate())

Open in new window

When I run that command it says 'syntax error'

I am trying to run these commands in a statistics program called SAS although the command window says PROC SQL - is this why the commands are not running?

those command should run in SQL Server, not familiar with PROC SQL.
